A jack 14 is placed beneath each needle 'in the same groove therewith andf has a dow-nwardly projecting lugr 15 passinothrough an opening in the needle b ed an Within the field vof the pattern lchains carried by the l1o drums 16' and 17.

A spring 18 is provided for each needleand sovplaced as to beardown u on'the same,

thus tending to force the shan of the'needle.

andthe jack beneath'it downward-and carry '15 Vthe lug 13`out of the .field ofthe ca ms 19 or20.

These cams 1Q-"and 20 are secured to'their rures ectivecarri'ages 6 and 7, 'and as they'are `bot alike in construction 'and-"operation: a

description of thel'one designated 19 and- 20 shownin detail in Figs. 11 and 12 will serve as .a description Aof both. Each vof these cams .consists of stationary anle blocks- 2 2 `fand '23, and'these last'4 named 'secured to the. camframe by pins 24 'which pass throughinclinedslots 25, .sc that whentheyare moved-up or down their mueredgesV will always remain in parallel with the outer edges of the stationary block 21, andatthe;

'and the loose' 'ss' of the stitch will be determined by the extent to which the blocks 22 and 23 are lowered.

. The movement ofthe blocks'22 and23 is 40 .controlled by the pins 26 which are set eccentrially in the ends Aof the short shafts '27 journaled in the cam frame-19 'and each of these shafts .carries .aV pinion 28. These pinions mesh with the teeth formed upon the' opposite sides ofthe rack har 29, so that when vsaid bar is movedupor downfthe A 30 by moving'the rackjbar will raise or lower asb'efre described. The rod 31 is journaled in the brackets 3 3, and carries upon one end thegear 34', it being lunderstood that there are two of these rods and gears, one-on'each side of the machine,

'y fand these gears mesh with the rack bar 35 blocks are' forth crosswise of the' machine, from which it -willb'e'fseen that'when'this' rack bar 35 is thus moved back o'r forth the gears Sltwill lbe revolved' in one or the-other direction bringing about the' adjustment of the @am as just described.

A jaccuard. heel 36 is secured'iuponlthe outer en l pattern chain drums and'has a series'of holes -37 in the face thereof in which are s et screw pins 88 at predeterminedpoints so that as this wheel is revolved the "pins set therein of one ofthe shafts whichdrive the will come in Contact with the 1ug39, dependl .ing from the rack bar 35, .moving saidbar in the direction'of the arrow marked thereon,A -and this will effectthe' rotation ofthe gear fit-heels 34 .inf one direction, and in order that the ra'okbar'mayfbe movedin. the opposite l direction' tofeiectv an opposite rotation --of these gear wheels, a jacquard chain.40 is 'carried bythe wheel 36, predetermined links Aofsaid chain lhavin suitable projections fthereonzfor striking t esmall roll journale'd ,linthelowerendof the lug 41; which 'also pro` jecjts downward 'froin the 'rack bar 35, thus 1- moving' this rack bar -in'the opposite fdirection from thejarrowmarked thereon. Thus '-itfwill be-seen that the arrangement of the screw pins and jacquard chainwill determine the adj ustmentof the needle cams to tighten orloosenjthe stitches taken by the needles.

Al'lher'e are two shorts-shafts 37 journaled in I 'the left handf'side of. the frame, and upon the rear one on .whicli'thejacquard wheel'36 is secured 'is also vsecured a 'ratchet wheel42,

and' upon the forward s ho'rt shaft 37 is seeured acorrespond-ing ratchet wheel.43 and the pawls 44 and 15 serve to lock these ratchet wheels respectively -`against reverse .movement, andin order that these ratchet wheelsmay be revolved step by step in the proper' direction. to revolve the needle pattern chain drums, a lever 46- is pivorted conentrio with V the ratchet wheel 43, and carnes a spring vactuated pawl 47v shown in dotted lines in Fig. 3, engaging with. the teeth of lsaid ratchet wheel, and this lever also carries ya -pawl 48;

which engages with the teeth ofthe lratchet wheel 42, so that when this lever is oscillated these two pawls will simultaneously revolve the ratchet wheels 42 and 4 3 step by step.

A four pointed' 01111148 is journaledupon I the stud 49, and 'the-gear wheel 50 is securedto thecarn fso as to revolve thelatt'er, said gear wheel meshing with the .pinion '51 car-- riedbythe; shaft ,'52, the latter runni 'lengthwise ofthe machine and having secure thereon thc worin; gear 53 which meshes :with the worm 54, said worm being secured 'act Ywhen said stud is swung within thefeld 4,5 in suitable bearing to rn'OVebaCk and'l of said points, the spring 57 drawing the 13o vvof action of the cam 48,.and as this earn is lever inward when said. lever 1s not locked out of the field of action of-t'he cani by the lock-lever 58, the function of fwhich will be next described.

The lock lever 58` is pivoted to the lever 46 by the stud 56, and has a series of notches 59 formed thereon adapted to en a'ge with the stud 49 which projects beyon v the housing 61 in which the cam and gear are inclosed,

.and the spring 57 is attached to the heel of the lock lever 58 in such manner as to cause the notched end thereof to be normally held down in engagement with the stud 49. When the lever 58 is locked in the position shown in Figs. 3 and 18, the points of the cam 48, will not act upon the st ud '56, or roll carried thereby 'and therefore. the lever 56 will re- .main a't rest, but when this -lever 58 is un'- locked the spring- 57 will draw the lever 46j inward bringing the stud 'within the field constantly revolving during the operation of the machine the lever v46 w1ll be moved back andforth by said cam in conjunction with the spring 57 as'long asl the lock lever 58 is held in an' elevated position, thus actuating the ratchet Wheels42'and 43;

' The' lock lever 58 is controlled 'bythe' lever 62', the ylatter being' pivoted u on the' stud 63 and connected with the lock. `ever 58 bythe .link 64 'so that whenthe lever A62 'is'. raised the lock lever 58' W'ill be raised, and the timesat. which the lever 62 is raised 'and 'the heights towhich it is raised is determined by the patternchain 65 carried in one of the grooves of the wheel 66, said chainA being provided with links of varying .th1ck nesses, someof said links havingonly'a p ortion thereof -'thickened and .when 'these thickened links or portions of links pass .,'under the toe 67 rojectin'g' from the lever 62, the latter will e raisedfto the predeter.-

By this form' ofdrum and pattern chain therefor any shape of garment may -be produced, and as the movements of this drum are under control, 'mechanism in turn controlled by a pattern chain it is obviousthat the wideningor narrowing' of-the fabric will take place at predetermined times, the drum and its pattern chains being intended to produce one cycle the knitting of the fabric, which will be repeated at every revolution of the drums as long as the machine continues to operate.
